Publication number: 20230364435Abstract: Techniques for switching an implantable medical device (IMD) from a first mode to a second mode in relation to signals obtained from internal sensors are described. The internal sensors may include a temperature sensor a biosensor and other sensors. In some examples, processing circuitry of the IMD may make a first preliminary determination that the IMD is implanted based on a first signal from one of the sensors. In response to the first preliminary determination being that the IMD has changed status, the processing circuitry may make a second preliminary determination that the IMD based on a second signal from the biosensor or some other sensor. The processing circuitry may switch the IMD from a first mode to a second mode based on both the first preliminary determination and the second preliminary determination being that the IMD has changed status.Type: ApplicationFiled: July 25, 2023Publication date: November 16, 2023Inventors: Robert M. Ecker, Matthew P. Hanly, Jerry D. Reiland, Hyun J. Yoon, Jon E. Thissen, Gary J. Pauly, Michael B. Terry, Ryan D. Wyszynski, Charles R. Gordon

Publication number: 20230285759Abstract: A device, such as an IMD, having a tissue conductance communication (TCC) transmitter controls a drive signal circuit and a polarity switching circuit by a controller of the TCC transmitter to generate an alternating current (AC) ramp on signal having a peak amplitude that is stepped up from a starting peak-to-peak amplitude to an ending peak-to-peak amplitude according to a step increment and step up interval. The TCC transmitter is further controlled to transmit the AC ramp on signal from the drive signal circuit and the polarity switching circuit via a coupling capacitor coupled to a transmitting electrode vector coupleable to the IMD. After the AC ramp on signal, the TCC transmitter transmits at least one TCC signal to a receiving device.Type: ApplicationFiled: May 18, 2023Publication date: September 14, 2023Inventors: David J.

Publication number: 20210267527Abstract: In situations in which an implantable medical device (e.g., a subcutaneous ICD) is co-implanted with a leadless pacing device (LPD), it may be important that the subcutaneous ICD knows when the LPD is delivering pacing, such as anti-tachycardia pacing (ATP). Techniques are described herein for detecting, with the ICD and based on the sensed electrical signal, pacing pulses and adjusting operation to account for the detected pulses, e.g., blanking the sensed electrical signal or modifying a tachyarrhythmia detection algorithm. In one example, the ICD includes a first pace pulse detector configured to obtain a sensed electrical signal and analyze the sensed electrical signal to detect a first type of pulses having a first set of characteristics and a second pace pulse detector configured to obtain the sensed electrical signal and analyze the sensed electrical signal to detect a second type of pulses having a second set of characteristics.Type: ApplicationFiled: May 14, 2021Publication date: September 2, 2021Inventors: James D.

Patent number: 10448855Abstract: In situations in which an implantable medical device (IMD) (e.g., an extravascular ICD) is co-implanted with a leadless pacing device (LPD), it may be important that the IMD knows when the LPD is delivering pacing, such as anti-tachycardia pacing (ATP). Techniques are described herein for detecting, with the IMD and based on the sensed electrical signal, pacing pulses and adjusting operation to account for the detected pulses, e.g., blanking the sensed electrical signal or modifying a tachyarrhythmia detection algorithm.
